The epistles, however, of Paul make themselves plain to those who wish to understand what epistles were sent by him, and from what place and for what cause. He wrote at some length, first of all, to the Corinthians, forbidding schisms and heresies; next to the Galatians, forbidding circumcision; then to the Romans, impressing on them the plan of the Scriptures, and also that Christ is the first principle of them, concerning which severally it is necessary for us to discuss, since the blessed Apostle Paul himself, following the order of his predecessor John, writes only by name to seven churches in the following order: to the Corinthians a first, to the Ephesians a second, to the Philippians a third, to the Colossians a fourth, to the Galatians a fifth, to the Thessalonians a sixth, to the Romans a seventh; and yet, although for the sake of admonition there is a second to the Corinthians and to the Thessalonians, but one Church is recognized as being spread over the entire world. For John, too, in the Apocalypse, though he writes to seven churches, yet speaks to all. Howbeit to Philemon one, to Titus one, and to Timothy two were put in writing from personal inclination and attachment, to be in honor, however, with the Catholic Church for the ordering of the ecclesiastical mode of life. There is current, also, one to the Laodiceans, another to the Alexandrians, [both] forged in Paul’s name to suit a heresy of Marcion, and several others, which cannot be received into the Catholic Church; for it is not fitting that gall be mixed with honey. The Epistle of Jude, no doubt, and the couple bearing the name of John are accepted in the Catholic [Church], and the Wisdom written by the friends of Solomon in his honor. The Apocalypse, also, of John and of Peter only we receive; which some of us will not have read in the Church. But the Shepherd was written quite lately in our times by Hermas, while his brother Pius, the bishop, was sitting in the chair of the church of the city of Rome; and therefore it ought to be read, indeed, but it cannot to the end of time be publicly read in the Church to the people, either among the prophets, who are complete in number, or among the Apostles. But of Valentinus, the Arsinoite, and his friends, we receive nothing at all, who have also composed a long new book of Psalms, together with Basilides and the Asiatic founder of the Montanists. (_b_) Irenæus, _Adv. Hær._, III, II:8. (MSG, 7:885.) The following extract illustrates the allegorical method of exegesis in use throughout the Church, and also the opinion of the author that there were but four gospels, and could be no more than four. It should be noted that the symbolism of the beasts is not that which has become current in ecclesiastical art.
